HAY- ELEVATO R.

SPECIFICATION forming part of Letters Patent No. 409,303, dated August20, 1889.

Application filed AprilZO, 1889. Serial No. 307,986. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM RODHAM, a citizen of the United States,residing at Shullsburg, in the county of Lafayette and State of\Visconsin, have invented a new and useful Hay-Elevator, of which thefollowing is a specification.

My invention relates to improvements in hay-elevators; and it consistsin certain novel features hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a view showing ahay-elevatorprovided with my improvements. Figs. 2 and 3 are enlargedside views of the pulley and its frame, showing the operation of thesame; and Fig. -t is a detail perspective View of the pulley and itsframe. Fig. 5 is at-ransverse sectional view on the line :0 a of Fig. 2.

The hoisting apparatus consists, essen tially, of the elevating-rope A,a pulley B, secured to a post 0 near the foundation or base of the barn,a pulley D, mounted in an arm E, projecting from the side of the barn,and a hay-fork F, secured to the end of the hoisting-rope, all of theusual or any preferred construction. At a suitable distance from theposts 0, and 011 opposite sides of the same, I erect the posts G G, andone of my improved pulleys is mounted on each of these posts.

The frame or bracket H, in which the pulley block or roller I issupported, consists of a U-shaped bar provided at its closed or bent endj with an eye or ring J, through which a suitable securing-rope ispassed to attach the said frame or bracket to-the post G. The upper armof this bracket is provided at its end with a longitudinal slot or notchK, which is engaged by the upper end of the shaft L of the pulley-blockI. The end of the lower arm of this bracket is curved downward, asclearly shown, and is provided with a longitudinal slot M, which isengaged by the lower angular portion of the shaft L of the roller. Thesaid lower portion of the said shaft is provided with a T-head Z, whichextends transversely beneath the lower arm of the bracket, and soprevents the shaft being withdrawn therefrom through the slot M. r

011 the upper side of the upper arm of the bracket I secure aspring-latcl1 N, which is provided near its free end with a perforationspring-latch is not material, as it is obviousthat minor changes may bereadily made therein without departing from my invention.

In practice the hoisting-rope, after passing under the pulley 13, iscarried to one of the posts G, and is passed around the pulley mountedon said post. The load of hayis then secured on the hay-fork in theusual manner and the horse driven toward the opposite post G, therebydrawing on the hoisting-rope, so

as to raise the load of hay in the usual manner. IVhen the load of hayhas been raised to the desired point and removed from the fork, the cordQ is drawn upward, so as to disengage the latch from the upper end ofthe shaft of the roller, when the roller will at once swing downwardaround the curved end of the lower arm of the bracket, out of engagementwith the notch in the upper arm thereof, as shown in Fig. 3. Thehay-fork then descends by reason of its own weight, the hoisting-rope ispassed around the pulley on the post G, which was formerly idle, and thehorse then driven'in the direction contrary to that in which he has justbeen driven. This operation is repeated until all of the hay has beenraised and stored in the barn, as will be readily understood.

It will be readily seen from the foregoing description, taken inconnection with the accompanying drawings, that I have provided anextremely simple device, by the use of which the travel of the horsewill be materially decreased, as when my pulley is used the horse raisesa load of hay when moving in each direction, instead of being forced totravel back to the starting-point after raising each load, asheretofore. The bracket supporting the, roller or pulley-block will hangslightly downward, so that when the latch is lifted the roller willpositively fall, so as to release the hoisting-rope The roller will beprevented from being lost by the T-head on the lower end of its shaft,and when the roller is raised and pushed up between the ends of the armsof the bracket the upper end of its shaft will be automatically andpositively engaged by the latch, so that it will be securely held.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

l. The combination of the frame having its lower arm provided with adownwardly-cu rved end and having a notch in the end of its upper arm,the roller having the lower end of its shaft mounted in the curved endof the lower arm of the frame and adapted to play longitudinallytherein, and having the upper end of its shaft adapted to engage thenotch in the upper arm of the frame, and the latch mounted on the upperarm of the frame and adapted to engage the end of the roller-shaft, asset forth.

2. The combination of the frame havingits lower arm provided with alongitudinallyslotted downwardly-curved end, and having its upper armprovided with a notched end, the roller having the lower end of itsshaft provided with a T-head engaging the slotted curvedend of the lowerarm of the frame, and having the upper end of its shaft engaging thenotched end of the upper arm of the frame, and a latch mounted on theupper arm of the frame and engaging the upper end of the roller-shaft,as set forth.

3. The combination of the frame, the roller having its shaft mounted inthelower arm of the frame and adapted to engage the upper arm of thesame, a latch mounted on the frame and adapted to engage the shaft ofthe roller to hold it Within the frame, and a cord secured to the latchto release the roller, as set forth.

4. The combination of the frame, the rollershaft having its lower endloosely mounted in the frame, and a latch mounted on the frame andadapted to engage the upperend of the roller-shaft, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

WILLIAM RODI'IAM.
